Pressure washers are an essential tool for every homeowner, but they can also be confusing. With so many different parts and variables to consider, it’s hard to know which one is the best choice. Luckily, it’s not as difficult as you may think! In this article, we’ll break down what features matter most when choosing a pressure washer and explain why each one is important for your cleaning needs.


You may have heard the term PSI as a measure of pressure, but what does it mean? PSI stands for pounds per square inch, and it’s a measure of the amount of force that is applied to a surface. A higher PSI means more pressure is being applied—more force pushing down on your car or home. The higher the PSI on your pressure washer, the cleaner it will be able to get at dirt and grime in corners and crevices.


GPM is the amount of water sprayed out of the nozzle. If you want to wash your car in a timely manner, you need to know how much PSI your pressure washer has. But there are other factors that can affect how long it takes to wash a car, such as:

  • The size of the power cord

  • The type and length of hose used

  • The nozzle being used (stream or soap)


Nozzle size: A nozzle is the tip of your pressure washer hose that sprays water. It can be adjusted to spray a wide or narrow stream of water, depending on what you’re cleaning and how much cleaning power you need. You’ll need to choose the right nozzle for each job, including ones for washing cars, decks, and driveways, as well as others for tasks like removing dirt from siding.

Brand: Most nozzles come with a brand name stamped on them; these are usually generic but still meet industry standards for quality and durability. Look for those with metal-reinforced stems because they’re stronger than plastic stems; this will help prolong the life of your product over time without breaking quickly under pressure from high water pressure from using too much soap or detergent during cleaning projects such as engine degreasing where chemical reactions occur between soap/detergent solution poured into engine bay during car washing process

The most important feature of a pressure washer is the pump, so make sure you clean it after each use.

The pump is the most important part of a pressure washer. In fact, it’s pretty much the only part—the water tank, hose and other accessories are more for convenience than for function. The pump creates the pressure needed to drive out any dirt and grime from your surface in question. It also generates the flow of water through your detergent injector (if you have one), which does all the work in terms of breaking down dirt and grime into smaller particles so they can be easily removed by your spray gun.

The most important thing to remember about this component is that its life will depend on how careful you are with it after each use. Make sure that when you’re done cleaning up, you clean out all excess water from inside your machine so none sits around inside while it drains away overnight or during storage periods between projects; otherwise it could cause corrosion or even rusting out on some components!
